Origen

“ Observe that when Plato says, that “after having found out the Creator and Father of the universe, it is impossible to make Him known to all men,” he does not speak of Him as unspeakable, and as incapable of being expressed in words. ”

“ Moreover, that these words, “He that hath seen Me, hath seen the Father who sent Me,” are not to be taken in their grosser sense, is plain from the answer which He gave to Philip, “Have I been so long time with you, and yet dost thou not know Me, Philip?” after Philip had asked, “Show us the Father, and it sufficeth us.” He, then, who perceives how these words, “The Word was made flesh,” are to be understood of the only-begotten Son of God, the first-born of all creation, will also understand how, in seeing the image of the invisible God, we see “the Creator and Father of the universe.” ”

“ He says: “since the wise men have found out this way, in order to be able to give us some idea of the First of Beings, who is unspeakable.” For ourselves, we hold that not God alone is unspeakable, but other things also which are inferior to Him. ”
